The average cost to build a porch really depends on what type of porch you want. Costs can range from a couple hundred dollars for a slab of concrete and a rail, to $30,000 or more for a fully enclosed wrap-around porch. Your choice of materials and whether or not you hire a contractor also affect the price.
Study Finds a New Treatment for Tinnitus. Tinnitus is a chronic and incurable condition that affects 5-to-15 percent of Americans. Characterized by phantom sounds such as whistling, clicking, or roaring, this disorder can be debilitating in its worst cases.
Hearing loss may have many different causes; but among tinnitus subjects, the major cause is cochlear damage. Ototoxic drugs (such as aspirin) can also cause subjective tinnitus, as they may cause hearing loss, or increase the damage done by exposure to loud noise. Those damages can occur even at doses that are not considered ototoxic. Tinnitus is also a classical side effect of quinidine, a Class IA anti-arrhythmic.
